For a project i need several PLCs (codesys 3.5) communicating with each other. We like to do that with TCP/IP.
We have to transfer structs with information. The structs contain arrays and normal variables.
The CAA Net Base Services looks the perfect library.
I downloaded the example program in the Codesys store. Every thing runs fine on a local soft PLC.
But when i make a project in the controller it self, the library gives a lot of errors.
When i choose "try to reload library" i'll get a pop up that the library is not installed om the system.
Does this mean that this library is not installed for this type of PLC?
Is the TCP/IP communication always availible on every type / brand of PLC in code sys 3.5?

Hi,
maybe this FAQ should explain why this could happen:
l viewtopic.php?f=22&t=5641&p=10085#p10085 l
Looking forward for 3.5SP5 to have a really good solution for this.
Which plc and which version of it are you using (the placeholders in the devicedescription are responsible for the library versions)?
